Junior Seau, who committed suicide in May, two years after retiring as one of the premier linebackers in NFL history, suffered from the type of chronic brain damage that also has been found in dozens of deceased former players, five brain specialists consulted by the National Institutes of Health concluded.

Seau’s ex-wife, Gina, and his oldest son Tyler, 23, told ABC News and ESPN in an exclusive interview they were informed last week that Seau’s brain had tested positive for CTE.

“I think it’s important for everyone to know that Junior did indeed suffer from CTE,” Gina Seau said. “It’s important that we take steps to help these players. We certainly don’t want to see anything like this happen again to any of our athletes.”

She said the family was told that Seau’s disease resulted from “a lot of head-to-head collisions over the course of 20 years of playing in the NFL. And that it gradually, you know, developed the deterioration of his brain and his ability to think logically.”

CTE is a progressive disease associated with repeated head trauma. Although long known to occur in boxers, it was not discovered in football players until 2005. Researchers at Boston University recently confirmed 50 cases of CTE in former football players, including 33 who played in the NFL.
